SPECIFICATION forming part of Letters Patent No. 419,545, dated January14, 1890.

Application tiled July 27,1889. Serial No.3l8,940. (No model.)

To all whom it may concern: v y

Be it known that we, ANDREW G. OLSON and JOHN S. LINDQUisT, bothresidents of Swedeburg, in the county of Saunders and State of Nebraska,have invented certain new and useful Improvements in Draft-Tugs; and wedo hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilledin the artto which it appertains to make and use the same.

The invention relates to improvements in draft-tugs, being designed toprevent the constant jerking' motion ofthe harness when traveling overrough roads, which motion is liable to cause the harness to abrade theskin ofthe horse or to produce the disease called swinney; and itconsists in the construction and novel combination of parts hereinafterdescribed, illustrated in the accompanying drawings, and pointed out inthe appended claims.

Figure l of the drawings represents a perspective view of the device.Fig. 2 represents an axial section thereof. Fig. 3 represents a similarsection of a modification of the device, and Fig. 4 represents detailsof parts of the device.

Similar letters ot' reference designate corresponding parts in thefigures of the drawings.

Referring to the drawings by letter, A designates the tubular casing ofthe device, having the centrally-perforated cap a secured to its top andthe bayonet-slot c extendingfrom its lower edge.

B designates a sleeve perforated centrally and having a pin b standingat right angles from its inner surface to engage within the bayonet-slota', and thereby to hold the sleeve B upon the lower end of the tubularcasing.

O is a rod that passes upward through the perforations in the cap a, andhas its end outside of saidcap threaded. The lower end of said rod O issecured by solder or otherwise within a thimble c, that is within thecasing A, and has at its lower end a circumferential flange c', whichstands normally in the sleeve B.

D is a rod within the caSingA with its upper end secured by solder orotherwise wit-hin' a thimble d, having at its upper end acircumferential fiange d', which stands normally in the cap a. The rodsO and D are therefore parallel or nearly so, and the threaded end of therod O is engaged by the hollow internally-threaded stem e of the ring orloop E outside of the cap a. The lowerthreaded end of the rod D isengaged outside of the sleeve B in the hollow internally-threaded boss fof the buckle F, which boss stands ce"n trally on the transverse bar fof said buckle. From the ends of the bar f depend the similar arms f2,one having an unthreaded perforation and the other an opposite threadedperforation. G is a screw that passes thro-ugh the said Unthreadedperforation and engages in the threaded perforation, thereby binding thearms f2 toward each other.

H is a coiled spring-that bears between the anges c and d of therespective thimbles c and d, so that the rods C and D can be pulledoutward from the respective upper and lower end of the casing Aagainstthe action of said spring. Y

Fig. 3 shows a modification of the device, in which the rod C isdispensed with, there being' but a single rod D. In this modificationthe ring or loop E is secured to the cap a.,

and the spring H at its lower end bears di'- l rectly against the sleeveB, there being` no thimble c. The loop orv ring E attaches to the tug ortug-chain and the buckle to the singletree, when the vehicle to whichthe horse is harnessed has a tongue.

In vehicles having thills the buckle is ati tached to the haines and theloop or ring to the tug. In this case the shell or casing A issurrounded by a cushion l, to prevent it from injuring the skin of thehorse.

Having described our invention, we claimv l. In draft-tugs, thecombination of the two parallel rods, the flanged thimbles secured tooppositeends of said rods, the ring or loop attached to the outer end ofone rod, the buckle attached to the outer or opposite end of the secondrod, and the coiled spring surrounding the two rods and bearing-againstthe flanges of the thimbles, substantially as described.

2. In draft-tugs, the combination, with the tubular shell or casing, theperforated cap secured to one end of the casing and the perforated shellattached to the opposite end of the casing, of the two parallel rods,the similarly-iianged thimbles attached to opposite TOO ends of saidrods, the loop ou the outer end of one of said rods, the buckle on theouter or 0pposte end of the second rod, and the coiled sp1-ingsurrounding' the rods between the flanges of the thinibles, substantially as specifled.

3. In a draft-tug, the combination, with the shell or casing A, havingthe perforated cap a on one end and the bayonet-slot a at the oppositeend, and the sleeve B, having' the pin b, to engage in said slot, of therods C and D, the thimbles c (l, respectively provided with the flangesc df, the ring or loop E, the

buckle F, having the screw G, and the coiled spring H, bearing againstthe flanges c d', all constructed and arranged substantially as and forthe purpose specified.

In testimony that We claim the foregoing as our own We have hereuntoaffixed our signatures in presence of two witnesses.
